Apple's Folding iPhone Is On Sale at $1,999. Early Screen Reports Are Worth Watching.
Apple's first folding iPhone, the iPhone Duo, went on sale on October 23, 2026. It starts at $1,999. The iPhone 18 Pro starts at $1,199, according to WSJ's shopping guide. That puts the Duo's extra cost at $800.
Apple announced the phone on September 9. It opened pre-orders on October 16, a week before the phone reached stores.
The phone has two screens. Apple describes a 7.6-inch inner screen, which you see when the phone is open, and a 5.4-inch outer screen. The outer screen covers 90 percent of the area of the iPhone 18 Pro's screen. Both screens share the same shape, and Apple says the inner screen is 50 percent larger than the one on the iPhone 18 Pro Max.
Inside, the phone uses the A20 Pro chip, which is its processor. Apple says a custom vapor chamber, a flat cooling part that spreads heat away from the chip, and a two-battery design help manage heat. Both screens support ProMotion, which refreshes the image more often so scrolling looks smoother. Both also support Always On, which keeps some information visible without fully waking the screen.
Apple rates the peak outdoor brightness at 3,000 nits. A nit is a unit of brightness, and a higher number means the screen is easier to read in direct sunlight.
Touch ID, the fingerprint reader, sits in the side button. You can also unlock the phone with an Apple Watch. The front camera for FaceTime sits beneath the inner screen when not in use. Apple says that, when opened, the Duo is the thinnest iPhone it has made. Apple Pencil support over USB-C is due later this year. The phone comes in star white and night sky. The Apple newsroom announcement also describes a nano-texture finish on the inner screen, a very fine surface pattern meant to reduce glare and minimize how visible the fold lines are.
Early reviews were mixed. Reuters reported that early reviewers praised the design and the hinge, which is barely visible. The same reporting said reviewers flagged camera compromises and noted that apps had not yet been adapted to the new display. Customers queued in Shanghai on October 23 to collect their orders, according to Reuters video coverage.
The bigger story is durability. Reuters reported on October 23 that Apple said it will replace iPhone Duo units showing screen problems. On October 27, the Wall Street Journal reported that Apple had acknowledged a problem affecting the inside folding screen on a small number of units.
Apple's support site already has a page titled "If your iPhone Duo won't turn on or the screens are black." It tells owners to charge the phone for one hour and then try again. Apple's separate iPhone Duo Repair Manual covers sound, battery, charging and power, Bluetooth or Wi-Fi, buttons, cameras, and cellular problems.
The broader context here is the folding screen itself. It has to survive thousands of open-and-close cycles at the hinge, much like a book spine that is bent again and again. The inner screen takes the most stress. Apple's answer to visible creasing is a surface finish, and its answer to a failing screen is a replacement promise. Neither one is a guarantee that the screen will last.
For buyers, the practical questions are what a replacement involves, how long it takes, and whether it goes through the same channel as a standard repair. Read those terms closely before you use a $1,999 phone as your everyday device.
For analysts, sales will depend less on the spec sheet. What matters is whether screen reports stay limited to a small group of phones, and whether app makers update their software fast enough that the larger screen becomes an advantage instead of a gap.
In my view, Apple's own framing puts the Duo in a new category. The price gap, the replacement promise, and the early app complaints make the next few weeks of sales and support calls matter more than they would for a normal iPhone launch.
